A Closed-Form Method With Low Noise Sensitivity for Locating a Moving Source on Earth at a Known Altitude

This article proposes a closed-form method that does not require an initial guess to determine the geographical location and velocity of a moving source at a known altitude. The primary objective of this method is to overcome the main limitations of the two-step weighted least squares (TWLS) method...
